The push rod of the buffer damper is riveted to one end of the transmission assembly. The cylinder of the buffer damper is fixed on the hinge base assembly. end. However, during the opening and closing process of the hinge cup, the buffer damper installation structure of the traditional hinge has the following shortcomings: 1) Since the buffer damper is installed at the end of the hinge base, the structure is complex and difficult to disassemble and assemble, and the linearly running buffer damper has always been Through the transmission assembly and the push rod, when the hinge cup is closed and opened at a certain angle, the linearly running buffer damper has a long buffering stroke, which makes it difficult for the buffer damper to always provide the corresponding buffering force as the hinge cup opens and closes, affecting Buffering effect, especially hinges with medium-curved arms and large-curved arms, are prone to jamming due to positional deviation between the buffer damper and the transmission component, resulting in the inability to open and close the door normally; 2) The buffer damper generally uses a buffer cylinder, and the cylinder of the buffer cylinder The body is fixed on the hinge arm, and the push rod of the buffer cylinder is in point contact with the torsion spring. It is easy to separate the push rod from the torsion spring due to vibration, which affects the stability of the buffer operation. Even, with the long use time, the torsion spring radially There will be a gap between them, and the push rod of the buffer cylinder is easy to insert into the gap, causing the buffering effect to fail and seriously affecting the normal use of the hinge.
